Well-designed lossy compression technology often reduces file sizes significantly before degradation is noticed by the end-user. The amount of data reduction possible using lossy compression is much higher than using lossless techniques. This is opposed to lossless data compression (reversible data compression) which does not degrade the data. The different versions of the photo of the cat on this page show how higher degrees of approximation create coarser images as more details are removed. These techniques are used to reduce data size for storing, handling, and transmitting content. In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content.
